CLOSURE DEVICE Filed Sept. 5, 1934 Patented Jan. 28, 1936 PATENT OFFICE CLOSURE DEVICE Edward E. Farley, Pocatello, Idaho Application September 5, 1934, Serial No. 742,821

1 Claim.

This invention relates to closure devices for collapsible tubes and its general object is to provide a device of that character, which is permanently secured to the tube to prevent loss thereof, yet can be disposed to open or closed positions instantly and by the finger or thumb of the hand holding the tube.

A further object of the invention is to provide a closure device that is designed to cut off the contents of the tube after the desired amount is dispensed, therefore eliminating waste and the accumulation of the contents about the outlet opening, as will be apparent.

Another object of the invention is to provide a tube closure device, that is simple in construction, inexpensive to manufacture, easy to assemble', and extremely efficient in use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a side view illustrating the application of my device to a collapsible tube.

Figure 2 is a front view thereof.

Figure 3 is a sectional view-taken vertically through the device with the cap in closed position in full lines and in open position in dotted lines.

Figure 4 is a sectional view taken at right is angles to Figure 3.

Figure 5 is a sectional view taken approximately on line 5-5 of Figure 4, looking in the direction of the arrows.

Figure 6 is an enlarged view of the device showing the manner of pivotally securing the cap thereto.

Referring to the drawing in detail, the letter A-indicates the body of a collapsible tube and B the shouldered portion thereof, which has formed thereon the bodv of my closure device.

The body of my closure device provides the neck of the tube and as shown includes a relatively large bore I extending vertically therethrough, for dispensing the contents of the tube as will be apparent.

The front wall 2 of the body 3, aswell as theside walls i are fiat, while the top wall 5 is round and merges into a rounded rear wall 6 which together with the top wall provides a seat for the cap '5. The cap I is substantially crescent shape in cross section with the concaved portion curved to follow the curvature of the top and rear walls, as best shown in Figure 3, and is of the same width as the body 3, in order to amply close the upper end of the bore I that extends through the 5 top wall as shown.

The cap is pivotally mounted to the body and for that purpose I employ a square cornered bail 8 that has a straight bight portion arranged in a groove 9 extending transversely of the top of 10 the cap, while the arms of the bail terminate in trunnions 10 which are received in bearing openings disposed in the side walls 4, as best shown in Figure 4.

By this construction, it will be apparent that 15 the cap is mounted for slidable movement on the rounded top and rear walls, and in order to limit the closed position of the cap I provide an abutment ll therefor, which is arranged in the path of the cap and transversely of the top wall at the juncture of the latter with the front wall, and a handle I2 is formed on and rises from the cap as best shown in Figure 3, it being noted that the handle I2 is disposed adjacent to the groove 9 and extends transversely of the cap.

The cap is easily mounted upon the body 3, and for that purpose I provide substantially triangular shaped grooves l3 disposed in the side Walls and extending from the front wall, with the apex portions of the grooves I3 terminating with the bearing openings as clearly shown in Figure 6. The tapering walls of the grooves l3 guide the trunnions H] to the bearing openings,

and due to the resiliency of the bail 8, it will be apparent that the trunnions will snap into the r bearing openings, with the result that the bail not only holds the cap I in tight association with the top and rear walls, but likewise pivotally secures the cap to the body 3. The groove 9 is of convexed formation, as shown in Figure 4 to al- 40 low the bight portion of the bail to bend downwardly into the deep end portions of the groove so that the cap can easily pass over the abutment It, in applying the cap to the body, and such will be apparent upon inspection of Figures 45 4 and 6.

From the above description and disclosure of the drawing, it will be obvious that I have pro vided a closure device for collapsible tubes, that is not only easily operated, but due to the particular shape of the cap 7, a cutting edge is provided to cut off the contents of the tube after the desired amount has been dispensed, which of course will eliminate waste and retain the 55 vided that such changes fall within the 10 closure device in a clean and sanitary condition at all times.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, proscope of the appended claim.

What I claim is:

A closure device for a collapsible tube comprising in combination, a body having a bore providing the outlet tor the tube, said body including curved upper and rear portions and flat front and side portions, and a cap having a groove there in and curved to follow the upper and rear portions for slidable movement thereon for controlling the bore, an abutment to limit the closed position of the cap, a handle for the cap, said body having bearing openings in the side portions and triangular grooves diverging from the openings to provide guides, a resilient square cornered bail having a straight bight portion received in the cap groove, trunnions on the bail and guided to the bearing openings by the triangular grooves in applying the cap to thebody and the cap groove being convexed to provide deep end portions to receive the corresponding ends of the bight portion to allow the cap to pass over the abutment during-the application or the cap to the body.
